Description

Technical Field

[0001] This utility model belongs to the technical field of gas detection equipment, specifically relating to a mobile platform for the accuracy detection of gas detectors. Background Technology

[0002] With the development of industrialization, air pollution is becoming increasingly serious, and the application fields of corresponding gas detection equipment are becoming more and more widespread. Diffusion-type portable gas detectors are widely favored by consumers due to their advantages such as small size, light weight, low cost, and simple operation. However, because the gas environments they detect are complex, these gas detectors require calibration after a period of use.

[0003] Traditionally, portable gas detectors are calibrated manually by holding the detector over a calibration device. However, due to significant individual differences, the distance between the detector and the standard gas is difficult to control, and the distance between the detector and the reflector is also difficult to adjust during testing. This results in large errors in the calibration results and reduces the accuracy of the portable gas detector. Utility Model Content

[0004] This invention provides a mobile platform for the accuracy detection of gas detectors, thereby solving at least some of the aforementioned technical problems.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0014] Furthermore, the fixed base includes a fixed connecting plate and two slide rod mounting seats disposed on the fixed connecting plate. The slide rod mounting seats are provided with mounting holes adapted to the slide rods, and the two slide rods are inserted into the corresponding mounting holes.

[0026] Example 1.

[0027] like Figure 1-4As shown, the present invention provides a mobile platform for measuring the accuracy of a gas detector, comprising a mounting frame 1, a fixing mechanism 3 slidably mounted on the mounting frame 1 for fixing a portable gas detector 20, a reflecting mechanism 2 slidably mounted on the mounting frame 1 for reflecting laser light, and a gas mounting mechanism 5 slidably mounted on the mounting frame 1 and located between the reflecting mechanism 2 and the fixing mechanism 3 for mounting a standard gas storage device 4.

[0028] The reflective mechanism 2 of this utility model is slidably mounted on the mounting frame 1, thereby adjusting the distance between the reflective mechanism 2 and the portable gas detector 20. The fixing mechanism 3 is slidably mounted on the mounting frame 1, and the portable gas detector 20 is mounted on the fixing mechanism 3 and moves synchronously with the fixing mechanism 3, thereby adjusting the position between the portable gas detector 20 and the standard gas storage device 4. The gas installation mechanism 5 is slidably mounted on the mounting frame 1 and located between the reflective mechanism 2 and the fixing mechanism 3. The standard gas storage device 4 is mounted on the gas installation mechanism 5 and moves synchronously with the gas installation mechanism 5, thereby adjusting the position of the standard gas storage device 4 on the mounting frame 1, so as to calibrate the portable gas detector 20 at different distances, thereby facilitating the determination of the detection accuracy of the portable gas detector 20.

[0029] In use, the reflective mechanism 2, the fixing mechanism 3, and the gas mounting mechanism 5 are slid together to adjust their positions on the mounting frame 1. The portable gas detector 20 is then activated, emitting a laser beam that passes through the standard gas storage device 4 and strikes the reflective mechanism 2. The reflective mechanism 2 reflects the laser beam back into the portable gas detector 20, thus revealing its detection structure. Since the gas concentration in the standard gas storage device 4 is constant, the result from the portable gas detector 20 is compared with the gas concentration in the standard gas storage device 4 to determine the detection error of the portable gas detector 20. This allows for calibration of the portable gas detector 20 based on the error value, thereby improving its calibration accuracy.
